Description

Technical Field

[0001] The utility model relates to the technical field of metal bone plate processing equipment, in particular to a polishing device for metal bone plate processing. Background Art

[0002] Metal bone plates are medical devices used to fix fracture sites and promote bone healing. They can also be used for joint fusion and surgical procedures involving osteotomy. They can be implanted in the human body or pass through the skin to apply tension (traction) to the skeletal system. Metal bone plates are usually made of high-strength metal materials, such as pure titanium and titanium alloys, stainless steel, cobalt-chromium-molybdenum, etc. These materials have certain flexibility and rigidity, and can effectively support and fix fracture sites. They need to be polished during the processing of bone plates.

[0003] The polishing device needs to be positioned before polishing the bone plate. Most of the polishing devices currently available on the market have a relatively simple structure and function, and can only position and polish the two ends of the bone plate. When the back of the bone plate needs to be polished, the personnel need to release the positioning, flip it over and re-position it, which greatly reduces the polishing efficiency, and the positioning operation of the personnel also increases the workload, resulting in a decrease in the practicality of the device. Therefore, we propose a polishing device for metal bone plate processing to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a polishing device for processing metal bone plates, which solves the problem that most of the existing polishing devices in the prior art can only perform positioning and polishing on both ends of the bone plate, and when the reverse side of the bone plate needs to be polished, personnel need to release the positioning, flip it over and re-position it, which greatly reduces the polishing efficiency, and the positioning operation of personnel also increases the workload, resulting in reduced practicality of the device.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

Specifically, the extrusion plate 12 is squeezed and positioned on the top of the joint bone plate through the positioning component, which effectively increases the positioning effect of the joint bone plate and adapts to bone plates of different heights and sizes to a certain extent. The effect of rotating the clamped and positioned bone plate is achieved by starting the rotating component, so that personnel do not need to release the positioning of the bone plate, flip it over, and re-position and polish it, thereby improving processing efficiency, reducing the operating burden of personnel, and improving the practicability of the device.

[0025] Furthermore, the positioning assembly includes a connecting plate 11 arranged on the top of the placement shell 10, and the connecting plate 11 is in an inverted U shape. The bottoms of both ends of the connecting plate 11 are fixedly connected to the top of the placement shell 10. A pull rod 13 is provided inside the connecting plate 11. The bottom end of the pull rod 13 passes through the top of the placement shell 10 and is fixedly connected to the top of the extrusion plate 12. The top end of the pull rod 13 passes through the top of the connecting plate 11 and a pull block is fixedly installed. Specifically, through the setting of the pull block, the pull block can be convenient for a person to hold the pull block and move it upward to pull the pull rod 13 to move to adjust the extrusion plate 12 to clamp and position and adapt to bone plates of different heights to a certain extent.

[0026] Furthermore, the positioning assembly also includes a spring 14 arranged on the top of the connecting plate 11, the interior of the spring 14 is nested with the exterior of the pull rod 13, and the two ends of the spring 14 are fixedly connected to the bottom of the pull block and the top of the connecting plate 11 respectively. Specifically, through the setting of the spring 14, a person can hold the pull block and pull the pull rod 13 upward to move, and the pull rod 13 then drives the bottom extrusion plate 12 upward. At this time, the pull block stretches the spring 14, and the person places the bone plate in the placement shell 10 and then releases the pull block to make the spring 14 lose its tension and elastically recover to pull the pull block and drive the pull rod 13 back, and at the same time make the extrusion plate 12 return to the top of the bone plate for extrusion and positioning, thereby effectively increasing the positioning effect of the bone plate and adapting to bone plates of different heights to a certain extent.

[0027] Furthermore, the rotating assembly includes a motor 8 arranged on one side of one of the mounting plates 7, and one side of the motor 8 is fixedly installed with the side wall of the adjacent mounting plate 7 through a bracket, and a rotating rod 9 is fixedly installed on the side of the two placement shells 10 away from each other, one of the rotating rods 9 passes through the adjacent mounting plate 7 side wall through a shaft sleeve and is transmission-connected to the output end of the motor 8, and the other rotating rod 9 is rotationally connected to the side wall of the adjacent mounting plate 7 at one end away from the placement shell 10. Specifically, through the setting of the rotating rod 9, by starting the motor 8 to drive one of the rotating rods 9 to rotate, even if the adjacent placement shell 10 rotates, the placement shell 10 immediately causes the other placement shell 10 to rotate through the other rotating rod 9 through the clamped and positioned bone plate, thereby achieving the effect of rotating the clamped and positioned bone plate, so that personnel do not need to release the positioning of the bone plate, flip it over, and re-position and polish it, thereby improving processing efficiency, reducing the operating burden of personnel, and improving the practicality of the device. Among them, the motor 8, cylinder 3, polisher 4 and hydraulic rod 6 are all connected through an external controller and a power supply, which is a prior art and will not be described here.

[0028] Furthermore, the bottoms of the two extrusion plates 12 are provided with anti-skid patterns. Specifically, through the provision of the anti-skid patterns, the anti-skid patterns can increase the friction force on the extrusion plates 12, so that the extrusion plates 12 can be more stable when they are extruded and positioned on the bone plates.

[0029] Furthermore, there are four supporting legs, and the tops of the four supporting legs are fixedly connected to the four corners of the bottom of the base plate 1. Specifically, through the setting of the supporting legs, the multiple supporting legs can provide a stable supporting force for the entire device, making the device run more stably.

[0030] In summary:

[0031] The personnel can start the two hydraulic rods 6 by external control and drive the two placement shells 10 to move closer to each other through the mounting plate 7 and the rotating rod 9, and then hold the pull block and pull the pull rod 13 upward to move, and the pull rod 13 immediately drives the bottom extrusion plate 12 upward. At this time, the pull block stretches the spring 14, and the personnel places the bone plate in the placement shell 10 and then releases the pull block so that the spring 14 loses its tension and elastically recovers to pull the pull block and drive the pull rod 13 back, and at the same time, the extrusion plate 12 returns to the top of the bone plate for extrusion and positioning, thereby effectively increasing the positioning effect of the bone plate and adapting to bone plates of different heights and sizes to a certain extent. By starting the motor 8 to drive one of the rotating rods 9 to rotate, even if the adjacent placement shells 10 rotate, the placement shell 10 immediately causes the other placement shell 10 to rotate through the other rotating rod 9 by clamping the bone plate in positioning, thereby achieving the effect of rotating the clamped and positioned bone plate, so that the personnel do not need to release the positioning of the bone plate, flip it over, and position and polish it again, thereby improving the processing efficiency, reducing the operating burden of the personnel, and improving the practicality of the device.
